Filled with memories of the Philippine campaign, Lieutenant Ranson returns to the United States. After a month or two in Washington, he tells his father that he must have a change, and a chance to see some excitement. General Ranson thereupon writes and arranges to have him go to Fort Stanton, Texas, an army post commanded by an old friend. Arrived at the railroad town nearest to the post, Ranson is conveyed to the post by stagecoach. A prairie fire is in progress a few miles away from Fort Stanton, and Ranson joins the soldiers and others in fighting it. Incidentally, he is successful in rescuing Mary Cahill, the daughter of the post-trader, Patrick Cahill. Ranson is received into the life of the fort and becomes a leader among the younger men. Ranson talks of the "big doings" out in the Philippines, and is "bored to death" with the dull routine of the fort.
